HOT-AIR HEATER.

SPEGlFIC'ATION lforming part of Letters Patent N o. 74 4,760, dated November 24, 190@ Application-tied october 16,1901. serial No. 78.859. m model.)

To all whom t may concern.-

Be it known that I, THOMAS B. JACKSON, a citizen of the United Statesfresiding at Bel-` mont, in the county of Belmont and State of Ohio, haveinvented certain new and useful Improvements in lIot-Air. Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to heating-stoves and it consists, essentially, of the novel construetion and arrangement of the various parts, as will be hereinafter fully described, and particularly stated in the claims.

The principal object of the invention is to heat cold air taken in at any" suitable point, preferably at the base, and discharge the same into the compartment in which the stove is situated or into other compartments desired to be heated. This and other objects of theinvention are attained by means of the device illustrated in the drawings, in which.-

Figure l is a front elevation; Fig. 2, a side elevation; Fig. 3, a vertical section on line 3 3 of Fig. 4; Figjl, a horizontal section on line 44 of Fig.2; Fig. 5, a detail section of the upper part of the stove-body and fuelmagazine; Fig. 6,'a perspective view of the fuel-magazine door, and Fig. 7 adetail showing the connection between the hot-airtubes or pipes of the upper and lower parts of the body. y p

In the several views, the letter a indicates the base of the stove, preferably cast in one piece, supported upon suitable legs c. The base is provided with the usual ash-pit-and draft-damper, as shown, and has each of its side walls provided with a series of vertical air-ducts a2, (only two beingshown,) through which cold air is taken from the outside.

The body of the stove is preferably composed of two sections band b, thelower section being provided with a suitable grate b2 and a door b3, opening i-nto the fire-pot. Each body-section'has its side walls provided with a series of oppositely-disposed air-tubes b4, fitted together, as shown in Fig. 7, and the upper section has a fuel-door b5 and a smokeout b. The upper end of the upper section immediately over the combustion-chamber is closed, and a cap c, provided with a register c', is litted thereon. The cap cis suiciently large to form an air-chamber c2, into which Hows the heated air from the tubes b4, and is provided with an opening c5, through which the heated air maybe conducted to warm other compartments. The air-tubes b4 are connected with the air-ducts a2k by means of short lair-tubes 277, thus forming a series of continuous air-tubes from the lower part of the stove-base to the chamber c2 in each side of the stove-bod y. The air-tubes a2 are pref'- erably inclosed by an air-chamber d, formed by a flaring-mouth cap d', into which chamber cold air is conducted through a suitable pipe d2. Supported in the upper part of the combustion chamber formed by the body-sections is a bell-shaped fuel-magazine e. This fuelmagazine is provided with a hinged door e', having sides e, which door when dropped or pulled down is adapted to engage the bottom of the fuel-door opening and form a chute, down whichthe fuel may be fed into said fuel-magazine. v

The'letter f indicates a water-heater, which is detachably supported inthe fire-box by means of the inlet and outlet pipesf andf2,

vwhich pass through the wall of the lower.

body-section and are screwed into the waterheater. The pipes f' and f2 may' be of a length suflicient to project a short distance beyond the outer side of the heater and have their outer ends screw-threaded to receive screw-threaded elbows, to which the feed and service pipes may be attached. By this construction it will be readily seen that the water-heater is suitably supported and rendered easilydetachable. v The water-heater is provided with a suitable draw-off cock f3 for the purpose of cleaning said heater.

Theoperation of my improved heater will be readily understood from the foregoing description, it only being necessary to state that when it is not desired to convey the heated air to another compartment any suitable'cap or cover may be fitted over the opening 03,

suitable damper placed in the conducting-4 pip@ g- It will be seen that my improved heater is of simple construction and may be readily taken apart for cleaning purposes or repair. The water-heater may be taken out when desired and the stove or heater used simply as a hot-air heater; but when the two, heating both air and water, are combined my stove or heater offers advantages not usually found in this class of stoves.

Having thus fully described my invention, what I claim, and desire to secure by Letters Pat-ent of the United States, is-

1. In a heating-stove, the combination with a suitable base having cold-air ducts, of two body-sections having a series of oppositelydisposed hot-air tubes formed Within their Walls, a series of independent tubes connecting each series of hot-air tubes with the coldair ducts, and a hot-air chamber situated above the upper body-section and communi- @ating With the hot-air tubes.

2. In a heating-stove, the combination with the base thereof, having cold-air ducts, of two body-sections having a series ot' hotair tubes formed Within their Walls, at opposite sides, the upper section provided with a fuel-door, a fuel-magazine, supported Within said bodysections, having a fuel-door adapted to rest upon the lower edge of the fuel-door opening in the upper body-section, and form a chute to convey the fuel to the magazine, air-tubes connecting the hotair tubes and the cold-air ducts, and a hot-air chamber above the upper body-section to receive the iiow of hot air from said hot-air tubes.

3. In a heating-stove, the combination with a suitable base provided with coldair ducts, of two body-sections having a series of hotair tubes formed within their side Walls, each series connected With the cold-air ducts by a series of independent tubes, a hot-air chamber, above the upper body-section, with which the hot-air tubes communicate, and a detachably connected water heater situated within the fire-pot.

et. In a heating-stove` the combination with the two body-sections having a series of oppositely-disposed hot-air tubes formed Within their Walls, a hot-air chamber situated above the upper body-section and communicating with the hotair tubes, of a suitable base provided with a series of cold-air ducts, a series of independent tubes connecting each series of hot-air tubes with the coldair ducts, and a cold-air chamber inelosing said cold-air ducts, said chamber having an air-inlet.

In testimony whereof I affix my signature in the presence of two witnesses.
